Alkylation of 2-methylthiopyrimidin-4(1H)-one (1a) and its 5(6)-alkyl derivatives 1b - d as well as theophylline (7) with 2,2- bis (bromomethyl)-1,3-diacetoxypropane (2) under microwave irradia-tion gave the corresponding acyclonucleosides 1-[(3-acetoxy-2-acetoxymethyl-2-bromomethyl) prop-1- yl ]-2-methyl-thio pyrmidin-4(1H)-ones 3a - d and 7-[(3-acetoxy-2- acetoxymethyl-2-bromomethyl)prop-1- yl]theophylline (8), which upon further irradiation gave the double-headed acyclonucleosides 1,1 ′-[(2,2- diacetoxymethyl)-1,3-propylidene]- bis [(2-(methylthio)-pyrimidin-4(1H)-ones] 4a - c , and 7,7 ′-[(2,2-diacetoxymethyl)-1,3-propylidene]- bis (theophylline) (9). The deacetylated derivatives were obtained by the action of sodium methoxide. The activity of deacetylated nucleosides against Hepatitis B virus was evaluated. Compound 5b showed moderate inhibition activity against HBV with mild cytotoxicity. Copyright Taylor & Francis Group, LLC.
